В сборник вошли статьи, посвященные разным аспектам палеонтологии и охраны уникальных местонахождений ископаемых животных и растений. Важное место в книге отведено вопросам музееведения, хранения и экспонирования палеонтологических коллекций, а также методическим приемам изучения различных ископаемых остатков.  Рассмотрены вопросы морфологии и систематики разных групп ископаемых организмов:  цианобионтов, аммоноидей, высших растений (сфенофиллов, птеридоспермов, гинкгофитов).
Книга предназначена для специалистов-палеонтологов, сотрудников профильных и региональных музеев, а также всех лиц, интересующихся вопросами естествознания и историей органического мира Земли.

These exercises have been made to fit the content of the book Pressure Control During Oil Well Drilling http://bookboon.com/no (a book that was revised and updated in 2011, mostly on basis of input from readers). Many of the exercises in present book have been solved by students in the corresponding course at the Department of Petroleum Engineering and Applied Geophysics at NTNU of Trondheim, Norway. It would be highly appreciated if you contacted me at pal.skalle@ntnu.no in case there is something unclear in this collection of exercises.

The enhancement of dissolution of quartz under the influence of clays has been recognized in sandstones for many years. It is well known that a grain of quartz in contact with a clay flake dissolves faster than when in contact with another grain of quartz. This phenomenon promotes silica transfer during the diagenesis of sandstones and is responsible of deformation and porosity variations. Here we make an attempt to explain the process of this rock deformation using a pressure solution mechanism.

This textbook is intended as an introduction to geochemistry for geology students in their senior year or in their first year of graduate work.At that time in their education, students are ready to relearn those principles of chemistry that are especially applicable to the study of geological processes. Geochemistry can enhance their understanding of these processes and can teach them to apply principles of chemistry to the solution of geological problems. Geologists in virtually all branches of the science can benefit from an introductory course in geochemistry because it can help them to make quantitative predictions about the outcome of chemical reactions that occur in the context of many geological processes <...>
